When the [START] key is pressed, the home position is checked in the first place, and the mirror
base performs A3 full scanning once at the set magnification ratio speed. During this scanning, the
set magnification ratio is displayed. The mirror home position sensor status is displayed with the
developer replacement required indicator.
(The lamp lights up when the mirror is in the home position.)
During scanning, the copy lamp lights up.
When the [Interrupt] key is pressed, the operation is interrupted to go to the sub code input standby
mode.
Used to monitor the mirror home position sensor. When the sensor is ON, the developer replacement
required indicator is lighted. During that time, the display section displays the sub code. When the
[Interrupt] key is pressed, the machine goes to the sub code input standby mode.
(When the CA key is pressed, the simulation is terminated.)
When the [START] key is pressed, the mirror base performs A3 full scanning at the set magnification
ratio speed. During scanning, the set magnification ratio is displayed. After 3 seconds, the mirror
base performs full scanning again. During scanning, the set magnification ratio is displayed.
* When the [START] key is pressed again, the START indicator turns and remains off.
The developer replacement required indicator displays the status of the mirror home position
sensor. (The lamp lights up when the mirror is in the home position.)
During aging, the copy lamp lights up. When the [Interrupt] key is pressed, the operation is
interrupted if operating, and the machine goes into the sub code input standby mode.
When the [START] key is pressed, the set magnification ratio is acquired and document transport
operation of single surface is performed in the case of SPF or document transport operation of
duplex surfaces is performed in the case of RSPF. Since, however, there is no limited condition for
this operation, it does not stop even at a paper jam. During operation, the LED on the display section
corresponding to the selected magnification ratio lights up, and the magnification ratio is displayed
on the 7-seg display. When the [Interrupt] key is pressed at that time, the machine goes to the sub
code input standby mode. When the [CA] key is pressed, the simulation is terminated.
<Conditions for executing this simulation>
Set paper on the SPF and fix it with tape. If paper is not fixed, the operations cannot be guaranteed.
(In order to receive the sensor change notification, the load must be decreased.)
The sensor status (ON/OFF) in the SPF can be checked with the following lamps.
When a sensor detects paper, it turns on. The open/close detection sensor turns on when the
machine is opened.
LED
Toner cartridge replacement required indicator
Misfeed indicator(Copier)
Developer replacement required indicator
Paper required indicator
Misfeed indicator(SPF)
Bypass tray indicator
Misfeed indicator(1st Tray)
AUTO indicator
TEXT indicator
PHOTO indicator
When the [Interrupt] key is pressed, the machine goes to the sub code input standby mode.
When the [CA] key is pressed, the simulation is terminated.
When the [START] key is pressed, the motor rotates for 10 sec at the speed corresponding to the set
magnification ratio. When the [Interrupt] key is pressed, the machine stops operation and goes to the
sub code input standby mode. When the [CA] key is pressed, the simulation is terminated.
The SPF paper feed solenoid (PSOL) is turned ON for 500msec and OFF for 500msec.
This operation is repeated 20 times.
After completion of the process, the machine goes to the sub code input standby mode.
When the [Interrupt] key is pressed during the process, the machine goes to the sub code input
standby mode. When the [CA] key is pressed, the simulation is terminated.
The RSPF reverse solenoid (PSOL) is turned ON for 500msec and OFF for 500msec.
This operation is repeated 20 times.
After completion of the process, the machine goes to the sub code input standby mode.
When the [Interrupt] key is pressed during the process, the machine goes to the sub code input
standby mode. When the [CA] key is pressed, the simulation is terminated.
Since the paper exit gate solenoid is abolished, even though the RSPF is installed, this simulation
does not work.
